Big Bang Theory Assignment

1) About how long ago did the big bang take place?
1.37 billion years ago.
2) What is a black hole?
Black holes are areas of intense gravitational pressure.

3) Does the universe continue to expand?
Yes, the weather is always changing because it use to be very small and really hot, but now it have expanded and it is cooling down.
4) Was there really a big bang?
Experters are saying that there wasn't an explosion.

5) What light elements seem to support the Big Bang Theory?
Hydrogen and Helium Found In the Observable Universe are the thoughts that support The Big Bang model of the origins.


Time Keeps On Slippin

1) What is the current calendar most of the world uses / accepts? Explain who made it and why this is accepted.


2) What is a leap year?
Leap year is a year that contains 366 days, with February 29 as an additional day: occurring in years whose last two digits are evenly divisible by four, except for centenary years not divisible by 400.

3) List three other types of calendars used and how they set up their calendar (ex. Lunar).

1. The Catholic Church maintained a tabular lunar calendar, which was primarily to calculate the date of Easter, and the lunar calendar required reform as well.

2. A perpetual lunar calendar was created, in the sense that 30 different arrangements (lines in the expanded table of epacts) for lunar months were created.

3. Lunisolar calendars these calendars aim to be both solar calendars and lunar calendars, but are more successful in tracking the seasonal cycle than the lunar cycle.

4) What is BC?
Before Christ


5) What is BCE?
Before Common Era

6) What is AD?


Anno Domini or Year of our Lord referring to the year of Christ’s birth.

7) What is CE?
Common Era

8) What is MYA?
Million Years Ago

9) According to the timeline site how many periods of when are there and list time.
Big Bang• Bronze Age • Byzantine• Cambrian • Enlightenment • First Settlements • Formation Earth • Hellenistic Age • Ice Age • Industrial Age• Iron Age • Mesozoic• Middle Ages • Permian • Reformation • Renaissance • Roman Age • Stone Age • Future

10) What is an eon, epoch, era, and age?

Eon: the longest division of geological time

Epoch: a period marked by distinctive character or reckoned from a fixed point or event
Era: period marked by distinctive character or reckoned from a fixed point or event
Age: how long something has existed; "it was replaced because of its age"

11) List three ancient calendars

-The earliest Egyptian calendar [Ref.] was based on the moon's cycles, but later the Egyptians realized that the "Dog Star" in Canis Major, which we call Sirius, rose next to the sun every 365 days, about when the annual inundation of the Nile began. -Celestial bodies — the Sun, Moon, planets, and stars — have provided us a reference for measuring the passage of time throughout our existence. Ancient civilizations relied upon the apparent motion of these bodies through the sky to determine seasons, months, and years. -The Babylonians (in today's Iraq) used a year of 12 alternating 29 day and 30 day lunar months, giving a 354 day year. In contrast, the Mayans of Central America relied not only on the Sun and Moon, but also the planet Venus, to establish 260 day and 365 day calendars.


12) List two ancient clocks and how they worked.

-Sun Clocks- Moving shadows formed a kind of sundial, enabling people to partition the day into morning and afternoon.Water Clocks these were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom.
-Water clocks- These were stone vessels with sloping sides that allowed water to drip at a nearly constant rate from a small hole near the bottom. Other clepsydras were cylindrical or bowl-shaped containers designed to slowly fill with water coming in at a constant rate. Markings on the inside surfaces measured the passage of "hours" as the water level reached them.

13) What was a revolution of timekeeping?
In Europe during most of the Middle Ages technological advancement virtually ceased.

14) What allows for standard more accurate clocks?
We have no evidence or record of the working models proceeding these public clocks which were wight-driven and regulated by a verge- and foliot escapement.

15) What are time zones?
A time zone is a region of the earth that has uniform standard time, usually referred to as the local time.
16) What is the prime meridian?
The Prime Meridian is the meridian (line of longitude) at which the longitude is defined to be 0°.17) If it’s 10:00 AM in Regina, what time is it in Toronto? London? Moscow? Tokyo? Hawaii?
Toronto: 11:00 AM
London: 4:00 PM
Moscow: 7:00PM
Tokyo: 1:00AM
Hawaii: 6:00


18) What is Daylight Saving Time? Do we use this in Saskatchewan?
The change to Daylight Saving Time allows us to use less energy in lighting our homes by taking advantage of the longer and later daylight hours. No I don’t think we use Daylight Saving Time in Regina.

19) Is there a year zero?
No There Is Not A Year Zero.

20) Are we starting a new decade in 2010 or 2011?
In 2011

21) What is linear time?
Linear time is a concept whereby time is seen sequentially, as a series of events that are leading to
ward something: beginning, and an end. In Newtonian theory it is something absolute in reality, regardless of human perception.
22) What is cyclical time?
Cyclical time sees time as circular, not necessarily leading towards something, but repeating itself in a cycle of events.
